Restoration planting options for Pinus flexilis James in the southern Rocky Mountains
Pinus flexilis James populations in the southern Rocky Mountains are severely threatened by the combined impacts of mountain pine beetles and white pine blister rust. P. flexilis' critical role in high elevation ecosystems heightens the importance of mitigating threats to P. flexilis survival. To …

Spatial accumulation patterns of snow water equivalent in the southern Rocky Mountains
… at which snow accumulation patterns across the southern Rocky Mountains vary abruptly. The concurrent accumulation period from SNOTEL stations were paired one-by-one until all 90 stations were compared among each other for all years on record. This comparison generated a relative accumulation …

Forest recovery trends following an unprecedented mountain pine beetle outbreak in the southern Rocky Mountains
… beetle (MPB) outbreak in the early 2000s in the southern Rocky Mountains, questions remain about what the structure and composition of lodgepole pine forests will look like as they recover. I used Forest Inventory and Analysis data collected by the US Department of Agriculture Forest Service, …

Evaluating and correcting sensor change artifacts in the SNOTEL temperature records, southern Rocky Mountains, Colorado
… the snow telemetry (SNOTEL) network across the Southern Rocky Mountains in the western United States have high warming rates, which may have been affected by systematic inhomogeneities in the temperature data caused by sensor changes. This study evaluates the maximum, average, and minimum …

Sedimentology, ichnology and sequence stratigraphy of the Lower Cambrian Gog Group, southern Rocky Mountains, Canada
… of sandstone bodies in the Gog Group of the southern Rocky Mountains of western Canada record the dynamics of sand movement on the broad continental shelf of West Laurentia during the Early Cambrian phase of worldwide transgression. This study focuses on the stratigraphy, sedimentology and …

Stratigraphic signatures of convergent orogenesis from the plate interior : studies from Tibet and the southern Rocky Mountains
… in the Qaidam basin of northern Tibet and the southern Rocky Mountain basins of North America, we provide new constraints on the timing of deformation, the development of proximal basins, and the evolution of continental-scale drainage patterns in two of the most prominent modern mountain …

Decreasing stream habitat for Greenback cutthroat trout under future climate projections in headwater streams of the southern Rocky Mountains, Colorado
… (GBCT) occupying the headwater regions in the Southern Rocky Mountains. Thus, this study used field data collected in the summers of 2019 and 2020 from selected headwater streams across the Front Range in the Southern Rocky Mountains to construct one-dimensional hydraulic models (HEC-RAS) to …

Whole genome sequencing to characterize Cutthroat Trout populations across the Continental Divide
… recognized lineages believed to be native to the Southern Rocky Mountains. Despite almost a decade of genetic and morphological studies, clarity on the phylogenetic history and evolutionary differences between all lineages of Colorado's Cutthroat Trout remains to be resolved and has implications …

Comparing crown fire predictions in ponderosa pine stands among four fire behavior models
… untreated ponderosa pine forest stands in the southern Rocky Mountains. All four models predicted crown fire occurrence for 71% of simulations in total. WFDS, QUIC-Fire, and CFIS agreed on fire type more than 65% of the time. Rothermel predicted crown fire for 41% of simulations with ROS …

Fire, climate, and forest structure in ponderosa pine forests of the Black Hills
… ponderosa pine forests in the southwest US or southern Rocky Mountains, these communities burned less frequently. Surface fire frequency varied from an average of every 10 to 13 years at lower elevation sites on the ponderosa pine - northern Great Plains prairie ecotone to as much as 30 to 33 …

Dynamics of water, carbon, and nitrogen in forest and alpine tundra ecosystems in the Pacific Northwest and the Rocky Mountains of the U.S. under future climate change
… a subalpine forest near Niwot Ridge in the southern Rocky Mountains of Colorado. Necessary improvements of the model were made on processes that are important in subalpine forests but negligible in other ecosystems such as soil evaporation. The analyses using the Budyko curve suggest that …
